Murphy's law says: the skills of the cameraman will be inversely proportional to the value of the presentation.

At least, the sound is clear. 😅

One way of explaining Clojure references could be the TV show Bewitched. "Darrin" the husband character is like a reference. "Darrin" referred to Dick York at first, then Dick Sargent later on. At no point did the production staff mutate Dick York into Dick Sargent.

Rich offers a great explanation here. This is less than 250 lines of code in Clojure, but has anyone tried building this same demo in Java using the Hystrix library? I'd be interested to know how many lines of Java would be required to obtain the same result. I'm guessing probably 2 or 3 times more...?

What are you objectively trying to imply with lines of code? When you're comparing a dynamically typed language vs a statically typed one the latter will be longer by default. Less line of codes doesn't imply it's more readable, doesn't imply it's faster, doesn't imply it's safer... etc

@@marcelofernandes6501 On the metric that says number of errors per thousand lines of code is constant across languages fewer lines is safer - for bugs, security, whatever else errors imply.
